There are many ways of doing this. Please give us more detail about your problem.

Which deterministic algorithm do you want?

I want to generate a unique sequence zeros and ones. The length of the vector is 100 for example. I want to do it using one or two commands. Every time I run it , it gives the same sequence.

Example a=[ 1 0 1 0 1 0 1 0.......] with length n=100.

Thanks

在 MATLAB Online 中打开

oldstate = rng('twister', 54321); a = randi([0 1], 1, n); rng(oldstate);

This line is not working.oldstate = rng('twister', 54321);

its giving me :

Error using rng (line 125)

First input must be a nonnegative integer seed less than 2^32, 'shuffle', 'default', or generator settings captured previously

using S = RNG.

在 MATLAB Online 中打开

oldstate = rng(65432, 'twister'); a = randi([0 1], 1, n); rng(oldstate);

I choose an initial seed that happens to give exactly 50 1's and 50 0's for n = 100.

Thanks for your help. I tried many times. Each time, it gives me the same sequence. Thats exactly what Iwant. One question if I want the sequence like [1 0 1 0 1 0 1 0 .....] is this possible?

Thanks
